New Zealand on a Japanese Licence — Same Side, Single-Lane Bridges

Here is the reassuring part for a Japanese driver heading to New Zealand: you stay on the left, just as you do at home. The single hardest thing most foreign visitors wrestle with — flipping every reflex to the opposite side of the road — simply is not on your list. Roundabouts turn the way you expect, the driver’s seat is where it should be, your mirror-and-shoulder routine still works. That frees up all your concentration for what New Zealand actually throws at you.

And what it throws at you is geography. Outside the cities the roads are narrow, winding and slow — a 280 km trip on the map can swallow a whole day once you factor in mountain switchbacks and coast roads with no straight sections. The classic surprise is the one-lane bridge, common on rural routes: a sign tells you who gives way, and a smaller arrow pointing your direction means you yield to oncoming traffic. Slow to a crawl, look right through to the far side, and be ready to stop. Plenty of back-country roads are unsealed gravel too, where braking distances stretch and rental insurance often excludes you — check your policy before you turn off the tarmac.

The paperwork is a firm rule rather than a tip. NZ Transport Agency accepts an overseas licence for 18 months from your last arrival (12 months from 1 November 2026), but only if it is in English or travels with an International Driving Permit or an accurate English translation. The Japanese card is not in English, so pick one. The permit issued in Japan is the 1949 Geneva version — Japan never joined the 1968 Vienna Convention — and New Zealand is a 1949 party too, so that permit is the natural fit. Carry it with the licence and your passport.

Speed limits are 50 km/h in town and 100 km/h on most open roads and motorways, with 110 km/h only on specially signed sections. Enforcement is camera-heavy. The drink-drive limit is 0.05, above Japan’s 0.03, and a typical speeding penalty is NZD 80 (about EUR 45) plus demerit points. The emergency number is 111, not Japan’s 110.
